The $2 Trillion Industry Everyone Is Talking About

The U.S.-based ETF industry passed a major milestone in 2014: $2 trillion in assets, up 18 percent from 2013.

That is quite a feat. In 2002, when I first mentioned ETFs, there was a mere $100 billion under management. By 2006 it had gone to $400 billion. By 2009 it had doubled, to $800 billion.

Now it's $2 trillion and counting, and that means one thing: The investment world is taking notice.
